The correct card for the PanelView Plus 400 and 600 terminals is 2711P-RN10C. The correct card for the PanelView Plus 700-1500 terminals is 2711P-RN10H. 7. Set the node address to 2, the communication rate to match the 1756-DNB DeviceNet module, and click OK. The General tab of the DeviceNet Scanner Properties dialog specifies the name, node address, virtual backplane slot, and communication rate of the DeviceNet scanner. The virtual backplane of the PanelView Plus has two slots. Because the terminal resides in slot 0, the DeviceNet scanner is automatically assigned to slot 1.

18 Configure the Terminal as a Slave Device Configure the Slave Inputs and Outputs You are now ready to configure the slave inputs and outputs in the PanelView Plus terminal. For the example used in this chapter, the 1756-DNB DeviceNet module will scan these inputs and outputs. One DINT or 4 bytes of input data One DINT or 4 bytes of output data IMPORTANT Typically these address blocks will be larger. Minimize the number of address blocks going to a single device. What differentiates the PanelView Plus terminal as a slave or a scanner is the node you specify for each block of data. The device you configure data for via the I/O Configuration tab is the slave on the network. If the device node matches the node address for the PanelView Plus terminal, then it will operate as a slave. In this example, the node address is 2. Definition of Inputs and Outputs Inputs and outputs are in reference to the PanelView Plus DeviceNet module and correspond to RSNetWorx terminology. In other words, the output of a controller is an input to the PanelView Plus terminal. RSView ME software can read inputs and outputs, but only write to outputs configured in the PanelView Plus terminal. Configure the Slave Input Data 1. On the I/O Configuration tab, right-click the Input icon and select Add Address Block.

Appendix A Restore Configuration to Local Tab In some cases, it may be necessary to edit an application after the DeviceNet configuration on the Local tab has changed or has been moved to a different computer. The RSLinx Enterprise Local tab configuration stays resident on the desktop computer, regardless of which application is being edited. Copy Configuration to Local Tab The following procedure shows how to copy the Target tab configuration for an application to the Local tab to allow for browsing for tags. IMPORTANT This procedure will overwrite all driver configurations on the Local tab with all of the driver configurations that were on the Target tab when the application was backed up. Make sure that the DeviceNet configuration is saved, make sure the application is backed up using Application Manager. When you are ready to resume editing, restore the application using the Application Manager. This will create an XML file with the restored I/O configuration. For RSView Studio software, you must complete the following steps. 1. Close RSView Studio software. 2. Disable the RSLinx Enterprise service within the Service Control Manager (Control Panel>Administrative Tools>Services). 3. Double-click RSLinx Enterprise. 4. Make a backup copy of the current RSLinxNG.xml file in C:\Documents and Settings\All Users\Application Data\Rockwell\RSLinx Enterprise. 5. Rename the Restored_restoredAppNAme_RSLinxNG.xml to RSLinxNG.xml. 6. Re-enable and restart the RSLinx Enterprise software. 71

72 Restore Configuration to Local Tab To allow browsing for tags, open the Communication Setup under the RSLinx Enterprise tree and apply the shortcut to the DeviceNet driver on the Local tab. If changes are made to the driver configuration on the Local tab, be sure to copy this configuration to the Target tab using the Copy button on the Communication Setup dialog.
